1.With the key placed button side down on
a soft surface, use a small flat-bladed tool,
a fingernail, or the Tesla-provided tool* to
release the bottom cover.
*For convenience, Tesla provides a special
tool to make it easy to open the battery cover. This tool was included in the box
containing your key when Model X was
initially purchased.
Note: If a lanyard is attached to the key
(see Attaching a Lanyard on page 6),
you can release the bottom cover by
placing your thumb against the "X" on the bottom cover, then
firmly pulling the
lanyard toward you (hence pushing the
key
off of its cover). You can also pry the
cover off by placing a small flat-bladedtool, a fingernail, or the Tesla-provided
tool against the lanyard cord.
2. Remove the battery by sliding it out at an
angle.

Braking SystemsWarning: Properly functioning braking
systems are critical to ensure safety. If you experience a problem with the brake
pedal, brake caliper, or any component of
a Model X braking system, contact Tesla
immediately.
Model X has an anti-lock braking system
(ABS) that prevents the wheels from locking
when you apply maximum brake pressure. This
improves steering control during heavy
braking in most road conditions.
During emergency braking conditions, the
ABS constantly monitors the speed of each
wheel and varies the brake pressure according
to the grip available.
The alteration of brake pressure can be felt as
a pulsing sensation through the brake pedal.
This demonstrates that the ABS is operating
and is not a cause for concern. Keep
firm and
steady pressure on the brake pedal while
experiencing the pulsing.
The ABS indicator flashes briefly on
the instrument panel when you firststart Model X. If this indicator lights
up at any other time, an ABS fault
has occurred and the ABS is not
operating. Contact Tesla. The braking
system remains fully operational and
is not
affected by an ABS failure.
However, braking distances may
increase.
If the instrument panel displays this
indicator at any time other than
displaying
briefly when you first start
Model X, a brake system fault is
detected or the brake
fluid level is
low. Contact Tesla immediately.
Emergency Braking
In an emergency, fully press the brake pedal and maintain
firm pressure, even on low
traction surfaces. The ABS varies the braking
pressure to each wheel according to the
amount of traction available. This prevents
wheels from locking and ensures that you stop
as safely as possible.
Warning: Do not pump the brake pedal.
Doing so interrupts operation of the ABS
and can increase braking distance.Warning: Always maintain a safe distance
from the vehicle in front of you and beaware of hazardous driving conditions.
While the ABS can improve stopping
distance, it cannot overcome the laws of physics. It also does not prevent the
danger of hydroplaning (where a layer of
water prevents direct contact between the tires and the road).
Automatic Emergency Braking automatically
applies full braking in situations where a
collision is considered imminent (see Automatic Emergency Braking on page 109).
Warning: Automatic Emergency Braking
is not designed to prevent a collision. At best, it can minimize the impact of a
frontal collision by attempting to reduce
your driving speed. Depending on Automatic Emergency Braking to avoid a
collision can result in serious injury or death.
Brake Wear
Model X brake pads are equipped with wear indicators. A wear indicator is a thin metal
strip attached to the brake pad that squeals as
it rubs against the rotor when the pad wears
down. This squealing sound indicates that the
brake pads have reached the end of their service life and require replacement. To
replace the brake pads, contact Tesla Service.
Brakes must be periodically inspected visually by removing the tire and wheel. For detailed
specifications and service limits for rotors and
brake pads, see Brakes on page 184.
Warning:
Neglecting to replace worn
brake pads damages the braking system
and can result in a braking hazard.
Regenerative Braking
Whenever Model X is moving and your foot is
off the accelerator, regenerative braking slows
down Model X and feeds any surplus energy
back to the Battery.
By anticipating your stops and reducing or
removing pressure from the accelerator pedal
to slow down, you can take advantage of regenerative braking to increase driving range.
Of course, this is no substitute for regular
braking when needed for safety.
Note: If regenerative braking is aggressively
slowing Model X (such as when your foot is
completely
off the accelerator pedal at
highway speeds), the brake lights turn on to
alert others that you are slowing down.

Warning: In snowy or icy conditions
Model X may experience traction loss
during regenerative braking, particularly
when in the Standard setting and/or not
using winter tires. Tesla recommends
using the Low setting (see To Set the
Regenerative Braking Level on page 67)
in snowy or icy conditions to help maintain vehicle stability.
The Energy app displays real-time feedbackon the amount of energy being gained by
regenerative braking. You can also display the
power meter on either side of the instrument
panel by choosing Energy using the scroll
button on the steering wheel (see Steering
Wheel on page 47).
The amount of energy fed back to the Battery using regenerative braking can depend on the
current state of the Battery and the charge
level setting that you are using. For example, regenerative braking may be limited if theBattery is already fully charged or if the
ambient temperature is too cold.
Note: If regenerative braking is limited, a
dashed yellow line displays on the power
meter.
To Set the Regenerative Braking Level
You can use the touchscreen to change the
level of regenerative braking:
1. Touch Controls > Driving > Regenerative
Braking .
2. Choose from two levels:

Overview of Climate Controls
The climate controls are always available at the bottom of the touchscreen. By default, climate control is set to Auto, which maintains optimum comfort in all but the most severe weather conditions. When you adjust the temperature, the system automatically adjusts the heating, air
conditioning, air distribution, air circulation, and fan speed to maintain your selected temperature. To override these settings, touch Auto (see Customizing Climate Control on page 127).
The fan, heating, and air conditioning systems are powered by the Battery. Therefore, prolonged
use decreases driving range.
Note: The following illustration is provided for demonstration purposes only. Depending on vehicle
options, software version, market region, and settings, the information displayed may be slightly
different.
1. The front seats are equipped with heating/cooling pads. When operating, the top indicator
turns red when heating or the bottom indicator turns blue when cooling.
Note: If Model X is equipped with the optional cold weather package, you can also control
seat heaters in the rear seats, heated wipers, and heated steering wheel by touching Controls > Cold Weather (see Controls on page 119).
2. Touch the up or down arrow to set the cabin temperature. To apply a temperature setting to
both the driver and passenger side at the same time, touch SYNC TEMP on the temperature
popup that appears when you touch an arrow.
3. Touch the fan icon to customize and automate climate control settings for the front and rear
cabin. (See Customizing Climate Control on page 127.)
Note: Rear climate controls are available only if Model X is equipped with six or seven seating
positions.
4. The windshield defroster distributes air
flow to the windshield. Touch once to turn on, touch a
second time to operate the heating and fan at their maximum level, and touch a third time to
turn
off and restore the air distribution, heating, and fan to their previous settings.
5. Turn climate control system on/off.
Note: The label on this button says Keep Climate On if you have set the climate control system
to maintain your temperature settings when parked (see Customizing Climate Control on
page 127).
6. The rear window defroster warms up the rear window for 15 minutes, then automatically shuts
off. Exterior side mirrors are also heated.
Warning:
To avoid burns resulting from prolonged use, individuals who have peripheral
neuropathy, or whose capacity to feel pain is limited because of diabetes, age, neurological injury, or some other condition, should exercise caution when using the climate control
system and seat heaters.

About the Security SystemIf Model X does not detect a key nearby and a
locked door or trunk is opened, an alarm sounds and the headlights and turn signals
flash. To deactivate the alarm, press any
button on the key.
To manually enable or disable the alarm
system, touch Controls > Settings > Safety &
Security > Alarm . When set to ON, Model X
activates its alarm one minute after you exit,
the doors lock, and a recognized key is no
longer detected.
If your Model X is equipped with the optional security package, it includes a battery-backed
siren that sounds in situations where a locked door or trunk is opened and Model X does not
detect a key nearby. If the Tilt/Intrusion
setting is on, the siren also sounds if Model X
detects motion inside the cabin or if the vehicle is moved or tilted (for example, with a
tow truck or jack). To temporarily turn the Tilt/
Intrusion detection system
off, touch
Controls > Settings > Safety & Security > Tilt/
Intrusion > OFF . The Tilt/Intrusion setting is
enabled every time Model X is unlocked.
Note: If you plan to leave something that
moves, such as a dog, inside your locked

About the Battery
Model X has one of the most sophisticated
battery systems in the world. The most
important way to preserve the Battery is to LEAVE YOUR VEHICLE PLUGGED IN when
you are not using it. This is particularly
important if you are not planning to drive
Model X for several weeks. When plugged in, Model X wakes up when needed to
automatically maintain a charge level that maximizes the lifetime of the Battery.
There is no advantage to waiting until the Battery
